The Thai pharmaceutical manager murdered in a Scottish exhibition centre on Monday was a quiet, single woman who kept to herself, according to friends and colleagues. The body of Khanokporn Satjawat, 42, was found in the female toilets at the the Scottish Exhibition and Conference Centre in Glasgow where she was attending the 11th International Congress on Drug Therapy in HIV Infection. Her body was found in a pool of blood and she had suffered blows to the head and body. A G4S security guard, Clive Carter, 34, has been charged over the murder and is expected to make a second court appearance on Thursday. A spokeswoman for Bristol-Myers Squibb, the company Khanokporn worked for, said it was "shocked and saddened by the events surrounding our colleague's death". "Our thoughts are with her family during this difficult time and we are providing them with the support they need," said the spokeswoman. Before joining Bristol-Myers Squibb, Khanokporn worked for Japan's biggest drug company, Takeda Pharmaceutical Co, for eight months based in Bangkok. "She was a quiet person. I never saw her argue or fight with anyone at work," said a former Takeda colleague who identified herself as Nui.
